ALEXANDER, CRANE FLIES FR. S. CHILE & TIERRA D. FUEGO. 15 



påle brown areas, one subbasal, the other at about mid- 

 length of the cell. 



Abdominal tergites with the first segment gray pruinose, 

 the other segments with broad, brown sublateral stripes on 

 either side and a very narrow and indistinct påle brown 

 dorso-median stripe; these sublateral stripes are narrow on 

 the basal segments but broaden out behind, on the seventh 

 segment almost suffusing the tergite; lat eral margins broadly 

 påle; sternites duU yellow with a narrow påle brown stripe 

 that begins as a brown spöt on the second sternite, conti- 

 nued caudal but on the fifth to seventh sternites being 

 represented only by a short basal line on each sternite. 

 Ovipositor with the flattened sternal valves extending to a 

 little beyond one-half the length of the straight, slender ster- 

 nal valves. 



Habitat. — Chile. 



Holotype, $, (P. Dusen); the specimen was presumably 

 taken in southern Chile together with the other material 

 secured by Dr. Dusen. 



Type in the Riksmuseum in Stockholm. 



Tipula chilensis is very closely related to T. philippiana 

 Alex. (Province of Santa Cruz, Patagonia). The påle basal 

 antennal segments and the peculiar praescutal pattern of gray 

 stripes on a dark brown background is shown by both spe- 

 cies. T, chilensis has the median praescutal stripe more 

 brown behind and with the wing-pattern much heavier, espe- 

 cially the subcostal spöts, the brown mark at the stigma 

 and in cells JR2 and R3, the much greater amount of brown 

 in the posterior and anal cells; the white post-stigmal area 

 appears only as a narrow seam in the extreme outher end 

 of cell 2nd Ri, the extreme base of Rz and as a narrow oval 

 spöt near the base of cell R3. Tipula ona also has the wing- 

 pattern very much as in species of this group of the genus 

 but the thoracic pattern would indicate that it is not clo- 

 sely allied. 



Tipula bigotiana, sp. n. 



Antennae dark brown, the second segment dull yellow; 

 head reddish gray, with a brown median line; mesonotal 

 praescutum dark gray with four brown stripes; scutellum
